Agentic Workflow Architecture Diagram Template

What this template is for

An agentic workflow architecture diagram shows how an AI workflow plans a task, runs it as a loop of steps, and decides when it's done. Unlike a single agent diagram that centers on one reasoning core, an agentic workflow emphasizes orchestration: a trigger starts the workflow, a planner decomposes the task, an execution loop runs each step (execute → call tools → reflect), workflow state persists progress between steps, and a termination check loops back or emits output. Use it to design an automated workflow, document how a long-running agent process is orchestrated, or explain where state and the stop condition live.

When to use this template

• Design an automated agentic workflow before writing the orchestration code.
• Explain how a workflow decomposes a goal into steps and iterates until done.
• Document where workflow state is persisted between steps for a design review.
• Show the termination check that decides whether to loop again or finish.
• Trace why a workflow looped forever — was the stop condition ever reachable?
• Compare an agentic workflow against a single ReAct agent loop.

How to use it

1. 1Start with the trigger — a user request or an event that kicks off the workflow.
2. 2Add the planner that decomposes the goal into an ordered set of steps.
3. 3Draw the execution loop: execute step → call tools → reflect/validate.
4. 4Add a workflow state store that persists progress between steps.
5. 5Add a termination check (done?) that loops back to the planner or emits output.
6. 6Connect the loop-back path explicitly so the iteration is visible.
